Mites can be associated with other organisms as parasites, commensals, phoretic, among others, such as some Winterschmidtiidae that present cooperative relationships with solitary wasps (Eumeninae). These wasps have one or more cavities in their body surface that are capable of carrying mites, called acarinaria. Studies carried out in the northern hemisphere suggest that these relationships are species-specific. However, in South America, there are few studies in this field. Aiming to recognize and increase our knowledge of the species of solitary wasps from Brazil that are associated with mites, we examined 61 wasps belonging to 29 species and four genera from Brazilian museum collections. All of the specimens studied presented at least one type of acarinarium in their bodies. There were mites in all specimens of wasps, but not all of them were associated with an acarinarium. The mites belong to 11 different genera: six in Winterschmidtiidae (possibly cooperation relationships); one in Oplitidae (phoresy); one in Erythraeidae (parasitism); two in Acaridae (phoresy); and one in Histiostomatidae (phoresy). Detrended correspondence analysis and indicator species analysis were conducted to test the preference of the mite genera for species of wasp and for site (regions of the wasp's body). These tests were significant only for the mite genus Vespacarus preferring Parancistrocerus wasp species and the metasomal acarinaria. Some of the mites did not have a specific host, and some wasps carried more than one species of mite, differing from the specific interactions reported for the northern hemisphere.
